Diamond coated tip - Force modulation mode - Reflex coating

NanoWorld Pointprobe® FM probes are designed for force modulation mode imaging. The force constant of the FM type fills the gap between contact and non-contact probes. Furthermore non-contact or tapping™ mode imaging is possible with this AFM probe. All probes of the Pointprobe® series are made from monolithic silicon which is highly doped to dissipate static charge. They are chemically inert and offer a high mechanical Q-factor for high sensitivity. The tip is shaped like a polygon based pyramid with a height of 10-15 µm

For applications that require hard contact between tip and sample this probe offers a real diamond tip-side coating. This coating features extremely high wear resistance due to the unsurpassed hardness of diamond.
The typical macroscopic tip radius of curvature lies in the range between 100 and 200 nm. Nanoroughnesses in the 10 nm regime improve the resolution on flat surfaces.

The reflex coating on the detector side of the cantilever enhances its reflectivity and prevents light from interfering within the cantilever.

* Typical values

Diamond Coating

Diamond coating is an approximately 100 nm thick coating of polycrystalline diamond on the tip-side of the cantilever leading to an unsurpassed hardness of the tip. Figure 1 shows the raman spectrum of the coating verifiying true diamond.

Reflex Coating

Reflex coating is an approximately 30 nm thick aluminium coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever.
